  20 +Required properties:
  21 +- compatible: Must be "brcm,bcm6318-pinctrl".
  22 +- regs: Register specifiers of dirout, dat, mode, mux, and pad registers.
  23 +- reg-names: Must be "dirout", "dat", "mode", "mux", "pad".
  24 +- gpio-controller: Identifies this node as a gpio controller.
  25 +- #gpio-cells: Must be <2>.
